I've written about Open Culture before and I'm hoping most educators have at least heard of the resource, or have used their content in class or for professional development.
I've also been reading a ton about S.T.E.M. learning and careers, and the huge deficit our country will be facing in the many years to come if we don't promote and develop those fields of study for our students. With that being said, Open Culture has an amazing library of Science Videos that offer amazing content to excite young learners and potentially push them towards a degree/career in science. See an example below from NASA!
